Installation guidelines

Shell type switching power supply

The shell-type power supply consists of a metal case and a plastic case, and the internal PCB is wrapped in a case and is usually installed in the system cabinet.Mingwei Power is divided into two types according to the power rating and design concept: Cooling fan, the other is without a fan.


1. Before installing or performing maintenance work, disconnect the power supply from the application system and make sure that it does not automatically reconnect without notice!
2. Please attach the mounting screws to the internal components of the power supply to maintain a sufficient safe distance. Please refer to the package on the sample manual for the most suitable mounting screws. 'Buy the power supply for the use of Mingwei', please call 400 600 0430.
3. A non-standard installation direction or a power supply operating at high ambient temperatures can cause the temperature of the internal components of the power supply to rise and should be used in a load. Please install according to the optimum mounting direction of the specifications and determine the maximum power supply according to the temperature- Good work load.
4. Fans and vents can not have something to block, if there are other heat sources nearby, at least it should be kept with a distance of 10-15cm
5. The following is recommended wiring specifications
AWG 18 16 14 12 10 8
Rated current (A) 6A 6-10A 10-16A 16-25A 25-32A 32-40A
Wire cross-sectional area (mm square) 0.75 1.00 1.5 2.5 4 6
Description: The maximum inrush current is only applicable to the 1-4 core, 5 or more inrush current can not exceed 80% of rated current
Make sure that all wires of the wire are in the terminal block and that the terminal screws are tightened to prevent poor contact.
6. Please refer to this website for other information on the product


1. In order to prevent the risk of electric shock and burns, all power failure, please pass the qualified electrician inspection, it is strictly forbidden to remove the power shell.
2. Do not install the power supply in a humid environment and near water.
3. Do not expose the power supply to high temperature environments and near fire sources. Please refer to the specifications to determine the maximum ambient temperature for power applications.
4. The output voltage and output current can not exceed the rating range specified in the specification.
5. The ground wire (FG) must be connected to the ground. 'Buy the power supply for the use of Mingwei', please call 400 600 0430.
6. All power supplies are designed according to the EMC regulations, and can be supplied with a test report for the relevant power supply, as the power supply is only part of the application system.
